Dorothy put out a humming bird feeder and the frantic little creatures appeared immediately. I wondered how long they waited in the tree tops for us to hang the feeder. I did some research on the web and learned the birds that come to the feeder are the same ones that were here last year. They migrate during the winter as far south as Panama and in early spring start the trip north. When they arrive at the Yucatan Peninsula they eat until they weigh twice their normal weight and then begin the 22 hour flight across the Gulf of Mexico. When they arrive in Texas they are back to their normal weight and continue on until they alight on our feeder.
They're not the only birds that return to our house every year. We have a purple martin bird house and several families nest there each year. Purple martins are insect eaters and are said to devour their weight in mosquitoes every day. Not only do they eat on the wing, but they drink by dipping over a pond and scooping the water into their lower bill while in flight.
